Is this relation a function?

(10,6), (10,6), (9,7), (7,9), (6,10).

did you intend to list the same ordered pair twice, or is this a typo?

No two ordered pairs (i.e. different pairs) may have the same first term.
Is that true?

This is not a typo. The same point (10,6) is given on this list of points.

I don't follow. Is this a function or not? If not, why not? Thanks.

Those are not two pairs but one term written twice.

In that case, the relation is a function, right?

More important than knowing the right answer is knowing why the answer is right.

So tell us, why is this relation a function?

Each x-value is different making this relation is a function. Correct?
